Disappointing customer service from manager.

Gosh, how disappointing. I tried returning a Nescafé Gold refill that I bought 15 days ago because I bought the incorrect granuals, I needed the espresso. The shop attendant called her manager who appeared as if he already made up his mind and I was wasting my breath in asking to EXCHANGE the product, not return, just an exchange. He refused. I tried to explain that I tried exchanging it previously at the SuperSpar at Paddocks in Milnerton where I work and it didn’t seem to phase him. He advised that I should have exchanged it the day after purchase.As a nurse working 12 hour shifts I don’t always have the flexibility to be at the supermarket but he didn’t see to care. Anyway…. Lesson learnt. Never again SPAR, especially SPAR TYGER MANOR TYGERVALLEY.
